j IMPROVEMENT IN H'o'RsEs'HoEs'.

Specilication forming part of Letters Patent No. 183,230, dated October 10, 1876; application filed March 13, 1875.

' line ww, Fig. l. Fig. 3 is a detail perspective View of a winter-calli.

Similar letters of reference indicate corresponding parts.

The invention will rst be fully described, and then pointed out in the claim.

A represents a horseshoe, in the toe and heels of which are formed screw-holes to receive the screw-shanks of the calks. B represents a calk, which vis made with a screw shank to screw into the screw-hole of the shoe A. In the inner side of the calk B is formed a recess, b', to receive a screw, G, which is screwed. into a screw-hole formed in the body of the shoe A, in such a position that the said hole and the recess b in the ealk B may be in line with each other when the said calk is screwedA into the desired position. With this construction the screw C locks the calk B, so that it cannot turn to become loose, and the recess b in the cal'k B protects the screw (l, so that it cannot be injured or worked loose.

By placing the screw C at the rear of instead of in front of the toecalk B, it is relieved from a large share of the blows and wear which fall to the lot ot nails or other fastenings when placedin front, for the impact of the shoe upon the ground, especially in fast travel, or on rough or cobblepaved roadways, is with a forward motion, tending soon to wear away or strain so small a thing as a nail-head or screw-head; but by placing it behind the toe-calk it issaved from all blows and concussions arising from these causes, and still more when partially buried in a recess or groove, b. Again, when placed in front the shoe is rendered less durable at the part where it is most liable to rapid wearnamely, atits extreme forward curve-and for the reason thaty the hole to receive such nail or screw must be made between the extreme forward edge of the shoe and the toe-calk,

thus leaving a very 'narrow or thin part of the metal at that part, and likely soon to wear away, and at best to weaken the shoe materially, even when it is new. By my invention I need no screw-hole forward of the toecalk, and that portion may therefore be left, if desired, entirely solid. These are important practical advantages due to my peculiar construction, and to the mode of application of the toe-calk to the shoe-plate. Again, it willl be observed that in securing my toe-calk to the` shoe, or removing it therefrom when it vis on the hoof, nothing is needed but a common screw-driver or any device which will do the same duty, because it is not held to place by any nail driveninto the hoof, so that one toecalk can be substituted for another, a new one for an old one, or a suminer-calk for a wintercalk, by an inexperienced person or farm-boy, without the aid of a farrier, and without any possible risk of injury to the horse by driving or withdrawing nails injudiciously. Moreover, my toe-calk, when secured to the shoe,l is as iirm as if welded to it, while horse-nails will readily loosen, and a toe-calk held by.a loose nail becomes at once worthless 5 andif a toe-calk comes off in icy Weather it leaves the horse in a precarious condition, especially ifa l blacksmith be needed to replace it and none be near or accessible. the shoe-plate in any peculiar or unusual manner, as to any extra thickness or breadth, or with any projections or flanges in order to apply to it my toe-calk in the manner described.

The screw C I make preferably with a long a horse-nail driven into the hoof to lock both,

Nor do I need to form such nail passing through the shoe-plete near its edge lend in front of the toe-calks. I am also' aware tha-t toe-calks have been formed with a dovetal, and adapted to be slid laterally into a dovetailed recess out in the face of the shoe at a part made thicker-for that purpose, and that a heel-call; thus made and applied has been Imade with e groove in its inner side, but not in its rear face, and the heels of the shoe made With projections or flanges on their inner sides, adapted specially for such eel-calks. These, therefore, I do not claim 5 set forth.
